Sodium Hydroxide → (2R)-4-[2-(2-Aminopyrimidin-5-yl)-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-8-yl]-2-methylpiperazine-1-carboaldehyde

Reaction Steps

5-{8-[(3R)-3-Methylpiperazin-1-yl]-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-2-yl}pyrimidin-2-amine (101.9 mg, 0.21 mmol) was added to a tetrahydrofuran solution (5.0 ml) of 1H-benzotriazole-1-carboxyaldehyde (34.8 mg, 0.21 mmol) at room temperature and the resulting mixture was stirred for 105 minutes. The reaction mixture was poured into a 2 N aqueous sodium hydroxide solution and the resulting mixture was extracted with methylene chloride. The organic layer was dried over anhydrous sodium sulfate, the mixture was filtrated, the filtrate was concentrated under reduced pressure, and the resulting residue was purified by preparative thin layer silica gel chromatography (methylene chloride:methanol=10:1) to give the title compound (96.8 mg, 90%) as a pale yellow solid.
